SQLAlchemy is an Object Relational Mapper (ORM) that provides a flexible, high-level interface to SQL databases. It was discovered that SQLAlchemy did not sanitize values for the limit and offset keywords for SQL select statements. If an application using SQLAlchemy accepted values for these keywords, and did not filter or sanitize them before passing them to SQLAlchemy, it could allow an attacker to perform an SQL injection attack against the application. Updated packages are available from ftp.redhat.com.
